Answer: -9/7 or -1 2/7

Step-by-step explanation:

use slope formula

y2-y1/x2-x1

(x1,y1)(x2,y2)

substitute in and solve

8-17/8-1

-9/7

the slope is -9/7

Answer:

slope = m = -9/7

Step-by-step explanation:

(1,17) (8,8)

(X1, Y1) (X2, Y2)

slope = (Y2-Y1)/(X2-X1)

then

slope = m = (8-17)/(8-1)

m = -9/7

The equation d = 10h represents the number of miles d, that Jin travels in h (hours). If Jin cuts down the time it takes him to travel 30 miles to 1.5 hours, what constant is multiplied by in the new equation
Equation: d = ________ h

Answers

0.15 is multiplied by 10 = 1.5 hours
The filled spot will be 20 because 20 times h (1.5) equals 30(d). To solve divide 30 by 1.5 and get 20

Answer:

Step-by-step explanation:

a) 7(25) + 4(10) + 37(5)

   7(20) +7(5) +4(10) + 5(30) + 5(7)

   1.40 + 35 + 40 + 1.50 + 35

   1.75 + 40 + 1.85

   3.60 + 40

  4.00 = 400% of $1

b) 50 + 7(10) + 1.02

   50 + 70 + 1.02

  1.20 + 1.02

  2.22 = 222% of $1

c) 2.00 + 13(5) + 71

   2.00 + 5(3) + 5 (10) + 71

   2.00 + 15 + 50 + 71

  2.00 + 65 + 71

  2.00 + 1.36

  3.36 = 336% of $1

A has a higher percentage of dollar because 400%>336%>222%
